' cmmeareme- To all whomz't may concern:

Be it known that we, GEORGE WHITIAKER- HAneRnAvEs, ALBERT I-IARennAvEs,and ROB-- ERT HARGREAVES, all sub ectsof the Klng of Great Britain,residing at Brookhouse Lane,

Blackburn, inthe county of Lancaster, Eng-1 land, have invented certainnew and useful Improvements in CardingEngines,iofwhich the following isaspecification;

This invention relates-to carding engines and has for its chiefobject'to provide an improved arrangement-for simplifying andfacilitating the stripping; cleaning and .qgrinding operations whichwill dispense with :the necessity forltransferringithe stripping thrush.from the cylinder to the dofli'erto perforinthe stripping*operationsand. in like manner the grinding roller from the cylindertoithe v operation thereby reducing labor.

According to this invention means are i provided for detachably mounting:thestripping brush in the throat formed by the r dofie or cylinderandfor moving same into i .25

'onthe dofi'er and cylinder for stripping pur-- v poses and for raisingsuch brush out IOIllCOIl .contactvwith the .wire ofthe (card clothingtact therewith afterfthe stripping operation has been eflected or forcleaningpurposes,

the said brush being advantageously inclosed 7 within an air tight orc-losely fitting casing adapted to be connectedlwith an air suctionplantfor dust removing purposes.

Eachof these end frames has a curved. outer portionuof a somewhatlarger radius than, that of the stripping brush and the frames areformed .with slots 01 for the in-- sertion andremoval. of thebrushspindle a, slides (i being employed to close the greater portion of saidslots but leave a space d doifer to perform the grinding and casing in.accordance with this inven Specification of Letters Patent.

for the lifting and lowering movement of the splndle. The latter isconveniently supported at its end in a bearing a formed in a slide orarmo thatis slidable in a bracket of whlch is ad ustably mounted on oneof the exlstlng cylinder blocks 5 Each slide or frames and is "fittedwith one or more handles a for turning purposes, the arrangement beingsuch that when the handle is "turned? in one direction the eccentricslower :tlieslides or arms a? to 'bring the stripping brush intosimultaneous engagement with the 'cardw -re of the/cylinder andthedofier,

*and when turned 'in they other direction raise thestripping brush clearof such wire. To

. cause the stripping brushEto engage equally 'wlththe wireonthecylinder and dolferpthe slide, or arm at is made extensible at aand provided; with screw adjustment a and the bracket which carries sucharm is slidable on the cylinder block b fo moving the strippin brush .A=itow ard the cylinder 0r doffer as :may;befrequired; said movement beingconveniently effected by an adj usting screw 6 The space between the endframes is coveredv bythe cylinder anddofler plates dtctywith theexception of an aperture'ol which is large enough to admit a cylindrical'memberwhich may be either the stripping brush or agrindingrrollersubstituted therefor, and. is normally-closed by a curveddoor (Z which fits closely over the end frame and along thea'djacentedges of the cover plates 1 i di fo This door is advantageously hingedFig.2 is a front'view .ofone'endoithe.

apparatus, and Fig.3 is an end view -ofthe along itslower edge to theadjacent plate and a. convenient method of cleaning the stripping brushcomprises .a comb a which maybe hinged coaxiallywith the door, and

adapted to swing independently of the door, ;so thatthe comb may bemovedinto contact with the brush for cleaning purposes when the door isopened. i y 1: ,By thearrangement described all that isnecessary'toperform the stripping operation islto turnthe handle a tolower the brush ,into. thewireo-fthe dofl'er and cylinder and pluttherope or belt onto the pulley onthe strippingbrush spindle, one of suchpulleys being-conveniently mountedyat each end of the spindle- When thestripping operation is completed the brushis raised out of the wire andif it is desired to clean it thedoor is opened and the brush turned inthe opposite direction so that the backs of the wire run in contact withthe strippin comb, and as the latter is situated at the juncture of thehinge the material from the. brush is transferred onto the open door. Toeffect the grinding operation the brush is removed and a grinding rollersubstituted therefor, any adjustments that may be required beingeffected by the adjusting screws on the arms and brackets previouslydescribed. The cover plate or end frame is advantageously fitted with apipe connection d (Fig. 3) so that if it is desired to use the apparatusin conjunction with a suctiondust removing plant it only becomesnecessary to connect a flexible or other pipe with the aforesaid pipeconnection, the cover plate and end frames being constructed to make astight a fit as is practicable with the adjacent stationary and movingparts of the carding engine.

. Thewires of the stripping roller A are inclined forward in thedirection of rotation of the roller as shown by dotted lines in Fig. 1,and are made of suflicient length to enable them to act as hooks whichremove fiber simultaneously from the cylinder B and dofl'er C, andretain the fiber until it isremoved bythe comb a Heretofore, thestripping roller or brush has been used first to strip one of themembers A, C, and then transferred to the other member to strip thelatter.
